A system that has to work almost every month here
Cookeville asks for heat from October through April and cooling from May through September. That is 12 months, one system or the other running, with barely a break between them. Winter nights average 30°F, cold enough that a furnace or heat pump is cycling on and off most nights for months straight. Summer afternoons average 85°F, so the same equipment turns around and runs cooling all through the warmer part of the year.
Most homes here heat with electricity, so a new system needs to hold up under that kind of steady demand in both directions. Power does not always stay on. Twenty percent of Tennessee households went at least 24 hours without power in 2024, and this area has recorded 11 winter storms and 81 damaging wind events over the past ten years. Whatever gets installed should be sized right for both seasons and able to come back on its own once power returns.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, when the unit is old enough that parts are getting hard to find, or when a technician tells you the compressor or heat exchanger is failing. Age alone is a clue but not the whole answer. A furnace or air conditioner nearing the end of its expected life is more likely to fail on the coldest night or the hottest afternoon, right when you need it most. If a contractor has already patched the same problem more than once, that's usually a sign the next call will cost more than a new system would.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is usually the better move. A furnace and air conditioner installed years apart often were not matched to work together, and pairing an aging furnace with a new coil, or an old air conditioner with a new furnace, can mean one part limits how well the other runs. Homes here need heat from October through April and cooling from May through September, so neither system sits idle long enough to justify letting it fail on its own schedule. If one system is still young and working well, though, there's no reason to replace it just because the other needs to come out.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to the ductwork, gas line or electrical circuit, and the vent or flue. After that comes the startup check. The technician tests the ignition or the compressor, checks refrigerant charge if it's an air conditioner, and confirms the thermostat is talking to the new equipment correctly. The ducts stay the same in most installs, so the contractor also checks that airflow to each room is working the way it should with the new unit. A contractor walking your house beforehand will know what the job actually involves and can price it for your specific setup.
